Endwall profiling for the reduction of secondary flow in turbines [PDF]

, 2003
This thesis describes investigations into the use of a technique for improving the efficiency of axial flow turbines. The flow in the turbine component of axial flow machines is complex, with a number of three-dimensional features.

Development of a Method for Enhanced Fan Representation in Gas Turbine Modeling [PDF]

, 2011
A challenge in civil aviation future propulsion systems is expected to be the integration with the airframe, coming as a result of increasing bypass ratio or above wing installations for noise mitigation. The resulting highly distorted inlet flows to the
